My invention relates more especially to that type of brushes employed for cleaning floors and similar surfaces, and an object of the invention, among others, is the production of a brush of this type that shall be particularly'eiiicient in operation, and that vshall have novel features of construction whereby the brush'may be produced in a simple and economical manner. l

One form of brush embodying the invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in whichf Figure 1 is a top view of my improved floor brush; Y Y

A brush embodying the invention forming the subject matter of this application is comprised of a back of frame-like construction in which the cleaning element, usually composed of fibrous material, is secured, this frame including a plurality of channeled members from which the cleaning material projects, said channeled members being secured together by tie pieces and spacers to provide a rigid structure, and a bracket to which a handle is secured is also attached to the frame in a manner to strengthen it.

In the accompanying drawings the numerals 8 and 9 designate two channeled members, of substantially the same shape, except as to size, these members being preferably of oblong shape and endless in construction with serial no.v 216,099.

center and folded over an anchoring rod l1' that extends for at least the whole length of the brush material within the channeled member, the lips 12 of said channeled member being compressed closely against the cleanin material ,13 to rmly and securely hold itr within the channeled member.

The tie pieces and spacers 14, each of which possesses both of these functions, are preferably formed from sheet metal and each is bent into proper 15, which recesses are formed to correspond to the cross sectional shape of the channeled members 8 9. These tie pieces are lixed to vthe frameby springing them over the channeled members, and they may be located at such distances apart along the channeled members as may be desired, in the structure herein shown there being two of these tie pieces and spacers located one near each end of the frame, a-nd as shown in Figure l ofthe drawings. vA ny other suitable means forsecuring the tie pieces in place may be employed.

The bracket for securing the handle to the structure is formed from sheet metal 16 that is stamped to shape and comprising .side bars 17, from which clips 18 project, and end pieces 19 connecting the side bars. Handle supporting sections 20 project inwardly into the opening formed by the side bars and end pieces, and handle positioning sections 21 project from opposite ends of the plate. The sections 2O have handle locating lugs 22 projecting from their ends and holes 23 to form sockets to receive the outwardly bent ends of a connecting piece eX- tending from a handle, and as illustrated in dotted lines in Figures 5 and 6 of the drawings. The positioning section is'formed with positioning shape to provide recessesH a single plate of prongs 24,-25, the former being' i located at the outervsides of the section and the latter being 50 herein,

located at the inner sides of the section and provided with fingers 26 eX- tending toward each other, and as shown in Figure 7 of the drawings. Clips 27 also project into the central opening at the center thereof. i

, In forming the bracket the side bars 17 are bent at substantially right angles to the plane Iof vthe plate, grooves 4being. formed therein to receive the members 9. The clips 18`are also bent to form grooves to receive the channel members 8, and the clips 27 are bent to `form grooves to receive the channeled members 9. It will thus be seen that tie pieces'and spacers are embodied in this bracket construction as well as in the members 14. The handle supporting sections 2()` arevbent downwardly at substantially right angles to theend pieces andthe handle positioning sections are bent to overlie the endypieces 19. The locating lugs 22 are bent into the'position shown in Y Figures 5 and 6 of the drawings to form lugs to receive pivots 28 of a handle connector shown Yin dotted outlines in Figures and 6 of the drawings, thus locating the pivots opposite the holes 23 into which said pivots move by a springing action of the connector. Theselugs may also act to support the pivots in addition to their support in the holes 23. The lingers 26 are bent downwardly into the position shown in Figures 5 and 6' ofV 'the drawings, the arms 30of the spring connector being received against these fingers when said arms are in the notches 31, and thus take a part of the wear of said arms upon sai notches, as it has been found that in use the connector will more frequently be located in these notches than in the notches 32 at opposite sides of the notches 31, it being understood that the spring arms of the connector may be compressed toward each other torelease them from any of the notches and the connector being thenk swung on its pivot in the holes 23 sai-d arms Vmay be located in any of the other notches. While Vthe entire brush, frame and the bracket for securing a handle thereto, has been illustrated and described my invention resides in the construction of the brush frame only and does not embody the 'details of construction of the bracket for securing the handle. Y. v
